Simple to do. I over complicated things my first try but the easy way i did it was as follows.
- Scale your starter square to 8 (Eight) on the X axis and 8 (Eight) on the Y axis
- Intrude with I (i) by 0.1 (Zero Point (.) One)
- Extrude on the Z axis by 1 (One)
- Repeat as many times as you would like.
